摘要:
A dental flossing apparatus having a single continuous loop of dental floss passing freely through and held by apertures, which may be located either within the body of each of two rings, or in an eyelet on each of the rings, the rings being suitable for placing on the long fingers of both hands. One or both eyelets may have one end fixed to and continuous with the ring, and one sharply pointed end contiguous with, but not continuous with, the ring, with the pointed end pointing inwards such that its external side lies at an acute angle to the outer circumference of the ring, so that the floss can enter the aperture by being pulled through the contact point between the pointed end of the eyelet and the ring, but can't easily exit the aperture once inside.
